NumberField validation does not fire after override of afterRender

NumberField validation does not fire after override of afterRender

The code below was used to override the afterRender of Ext.form.Field to allow quicktips for the fields and their labels by supplying a field config option for quicktips (ex. qtipCfg:{title:"Title", text:"Text"}). The code was copied from another thread and modified slightly. It seemed to work fine. Then, I noticed that the field validators are not firing after overriding. Also, a NumberField will allow alpha characters after overriding.
